Abstract: A system for managing a computer network having a multiplicity of users, applications programs and servers, comprises a) user interface means for displaying a list of tasks appropriate to a given user at a given time, b) administration means comprising a software object including a set of rules defining the relationships between users, applications programs and servers, c) a module comprising database means and one or more LDAP compliant directories for storing user records, application program records, and server records, to enable updating of said records in a systematic way, and d) synchronisation means for managing the exchange of data between said administration means, module c), and the computer network. The administration means in use performs tasks such as user record or server creation, updating, and deletion; application program installation, commissioning, and program updating, in response to user input.

Abstract: An EPROM emulator makes use of a simple device with a housing connected to a eprom header which serves to connect the device to a circuit board in conjunction with a microprocessor emulator. Inside the housing are paging and data select circuits and a set of SRAM which are used in place of a traditional EPROM to hold the programming information. To program the device, the EPROM simulator is connected to the circuit board in place of an eprom. A switch on the housing is then turned to place the device in programming mode. The same switch also determines how the device is programmed by accessing the appropriate data lines for the number of pages of EPROM memory which are being emulated. After the switch is properly selected, the emulator is programmed by sending the data through the eprom socket on the circuit board via the microprocessor emulator. After the device is programmed, the switch on the housing is turned to place the device in read-only mode so that it can simulate an EPROM.
